METHOD FOR PREVENTING SPONTANEOUS IGNITION OF COAL, AND COAL MIXED FUEL PREVENTED FROM SPONTANEOUS IGNITION

摘要

PROBLEM TO BE SOLVED: To provide a method capable of preventing spontaneous ignition of coal by a simple method using no water, and to provide a coal mixed fuel prevented from spontaneous ignition.;SOLUTION: The coal mixed fuel 1 is produced by mixing a lump coal 2 with a lump material 4 such as carbonized biomass less oxidizable than the coal 2. The lump material 4 has a size suitable for filling a space 3 between the lump coals 2, and the lump coal 2 is at least one of bituminous coal or sub-bituminous coal.;COPYRIGHT: (C)2006,JPO&NCIPI
